How do I configure the Port Mapping feature to populate the Switch Inventory data?

1) Your switch must be present in your EventSentry configuration, in a Network Device group

2) Clicking Check Status > Go in the console toolbar must display the SNMP version information in the SNMP column

3) Your switch or its EventSentry group must be assigned a System Health package that contains the Inventory feature. This is usually the Inventory package (new installations of 3.2) or the General Monitoring package (upgraded from previous EventSentry versions)

4) Your switch must provide MAC to port mappings via SNMP (using OID : iso.identified-organization.dod.internet.mgmt.mib-2.bridge.dot1dTp.dot1dTpFdbTable.dot1dTpFdbEntry.dot1dTpFdbPort)

If your switch appears to meet all of these requirements but there is no data for it under Inventory > Switch in the Web Reports, you can try the SNMPinfo exe from our SysAdmin Utilities:

To run it, use the command prompt in this format:
snmpinfo /u mycommunity (replace "mycommunity" with your SNMP community name for the switch, and replace with the IP of your switch)

If you are running an older version of the SysAdmin Utilities, the exe had a different name so you'd have to run:
snmptool /u mycommunity

In the output, if you do not see a section for SWITCH PORTS, either this function is not supported by your switch or the community name you have selected does not have adequate permissions to read this data.

If you do see the SWITCH PORTS section but the Switch Inventory data is still missing, please try restarting the Heartbeat Agent on your EventSentry server. If refreshing the Switch Inventory page does not produce data after 10 minutes, please write the SNMPinfo output to a text file and then contact our support department to share the SNMPinfo data with us. To write the SNMPinfo output to a text file, you can use this example:
snmpinfo /u mycommunity > c:\temp\snmp.txt
(replace "mycommunity" with your SNMP community name for the switch, and replace with the IP of your switch)
